checkpolicy_selinux

NAME

DESCRIPTION

FILE CONTEXTS

SELinux requires files to have an extended attribute to define the file type.

You can see the context of a file using the -Z option to lsP
Policy governs the access confined processes have to these files.
SELinux checkpolicy policy is very flexible allowing users to setup their checkpolicy processes in as secure a method as possible.

The following file types are defined for checkpolicy:

checkpolicy_exec_t

- Set files with the checkpolicy_exec_t type, if you want to transition an executable to the checkpolicy_t domain.

Note: File context can be temporarily modified with the chcon command. If you want to permanently change the file context you need to use the
semanage fcontext
command. This will modify the SELinux labeling database. You will need to use
restorecon
to apply the labels.

PROCESS TYPES

SELinux defines process types (domains) for each process running on the system

You can see the context of a process using the -Z option to psP
Policy governs the access confined processes have to files.
SELinux checkpolicy policy is very flexible allowing users to setup their checkpolicy processes in as secure a method as possible.

The following process types are defined for checkpolicy:

checkpolicy_t

Note:
semanage permissive -a PROCESS_TYPE
can be used to make a process type permissive. Permissive process types are not denied access by SELinux. AVC messages will still be generated.

COMMANDS

semanage fcontext
can also be used to manipulate default file context mappings.

semanage permissive
can also be used to manipulate whether or not a process type is permissive.

semanage module
can also be used to enable/disable/install/remove policy modules.

system-config-selinux
is a GUI tool available to customize SELinux policy settings.
